SHIPPING BOX.

The invention relates to shi in` boxes` and more particularly to those boxes which are-formed of sheet material suchk as iibre board. f Hertofore, libre board shipping boxes have been impractical for use in shipping heavy articles because they wouldy break or crack due to the weight and pressure of the articles. Y c

Thev primary objectof the present invention is to providea fibre boardA shipping box whichwill withstand severe handling and will not break or crack when used for shippingheavy: articles. The top, bottom and sides of this box are constructed so that each consists of an inner and outer fibre board wall andseparately formed hollow cylindrical reinforcing members which are disposed between and are secured to the walls. v i

' Another object of the invention is to provide a libre board shipping box which may be readily hermetically sealed.

A further object of the invention is to '25 provide a shipping box which is of new and improved construction and can be produced at a low cost. n l

Other objects will be apparent from a consideration of the following. detail description.y i Y The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. f u 1 Inv the drawings: Fig. 1 fis a perspective ofalbox embodying the invention, portionsv being broken away for the purpose of illustration. Fig. 2 is a vertical section of the box.l Fig. 3 is a section on line 3 3 of Fig. 2. Fig. 4 is perspectivel of onegof the reinforcing members.V Figq is a section through-one of the handles forthe'box. Figs. 6 and v7 are detail perspectives showing modifiedforms of reinforcing members.

The invention isexemplitied in a rectan- `guiar shipping box comprising sides 10, a top 11 and abottom 12. Each side consists of` an outer wall 13' and anninner wall 14 rvwhich is spaced from the outer wall as hereinafter described. The outer walls 13 are formed from a stripof libre board which isy creased as at 15 to forni the corners of -thebox and has itsV end margins secured together-by a strip 16 of Aadhesive-tape. Theinner walls 14 are alsovformed of libre vided with upwardly extending marginal `walll22 a hollow compartment 11a.

board and each is separate from the others rand provided with a iap 17 at its top inargin, a liap V18 at its lbottom margin, and flaps 197 20 at its side margins. These liaps extend outwardly and have their outer edges glued "to walls 13. They ser-vey as spacing means for inner walls 14, and form with the latter and the outer wall 13, hollow compartments 10a. Flaps 17 and 18 are iiush with' the top and bottom edges of outer walls l13 respectively. Flaps 19 are disposed inwardly of the side edges of the outerwalls-soas toexpose marginal portions 21 on thev inner faces of said outer walls. Each of the flaps 2O abuts against and is.` glued to the marginal portion' 21v on the outer wall 13 of the side which is contiguous to it. Eachof vthe fiaps 19 abuts against and is kglued toV one of `the side Vmargins of inner wall V14 of the `side .which is contiguous to it.V By gluing flapsl) and Haps 2O 'as set vforththe corners of the box arestrengthened softhat they will withstand severe handlingwithout breaking and will prevent thesidesfl() from collapsing. y

Top 11 consists of anfouter wall 22 and an inner wall ,23 both of which are formed of fibre board. The inner wall 23 is proflaps 24 which have their upper edges glued to wall 22. These flaps Yare spacedl inwardly from the edges of wall 22 and are adaptedfto engage the upper margins of walls 14 when the topcis in its operative position. Flaps 24 serve as spacingfmeans for Vwall 23 and form with the lat-ter and The exposed margins of wall 22 rest upon flaps 17 when the top is' in its yoperative position. 95 To secure'the topfin this position iiaps 24 are glued to the upper margins of walls 14 and iiaps 17 are glued to the margins of wall 22. To additionally secure top 11 in 'its-operative position, a pairof yextensions 100y 25 are provided. These. yextensions are `formed integrally with the outer walls 13 of two of the sides and are adapted toy be folded over outer 'wall 22. Extensions yand an innervtibre board wall 27 which is provided with downwardly extending flaps 1,10V

28. The latter form with walls 26 and 27 a hollow `compartment 12u. Flaps 23 are glued to the lower' margins of walls 14 and flaps 18 are glued to the exposed-mai gins of wall 28 so as to secure -the bottom in place. The bottom is additionally secured in place by a pair of vextensions 29 which are similar to extensions 25. These extensions are folded .over outer wall V26 and are secured together by any suitable means. spectively to strengthen the top and bottom of the boX. A characteristic of the specific flap construction set forth is that the tiaps, when glued respectively to the surfaces ad jacent them form a hermetical seal for the box.

In Figs. l to of the drawings, compartment-s l()a are shown filled with separately formed hollow reinforcing members 30. rlhese 1members eX-tend transversely to the compartments in which they 'are disposed and ext-end completely throughout the latters area. Members 3() have their sides glued together and their ends glued to walls 13 and 14: respectively. This makes sides l0 substantially rigid and reinforces them so that they are capable of rw-ithslanding great weight and pressure. Hollow compartments lla and 12a-are filled respectively with reinforcing members 3l land`32 which are similar to members 30. Members 3l have their sides glued together and their ends glued respectively to walls 22 and 23. Members 32 have their sides glued together also and their ends glued respectively to walls 26 and 27.

6 illustrates reinforcing members 33 which are of a slightly lmodified for-m. These members comprise hollow cylinders which extend parallel to the compartments. rllhe sides of members 33 are glued to each other and to the inner and outer walls of the compartment in which they are disposed.

Fig. illustrates reinforcing members 34 of lanother form. These members are semicylindrical and extend similarly Ato members 33. The edges of members 34 are glued to the outer wall of the compartment in which they are disposed and the sides are glued together and to the inner wall. A

To facilitate handling, the boi; is provid/ed with handles. These handles are disposed at oppositev sides of the bei: and comprise members 35 which entend through openings 36in walls 13. These members are disposed completely within compartments l()a and are surrounded by reinforcing members 30. They have finger openings 37 at one side thereof and are provided with flaps L38 which extend outwardly andare glued to the youter face of walls 13 so as to secure the members in place.

The invention exemplifies a fibre board shipping box which may be hermetically seailed and is so constructed that it will witharticles.

Extcnsioi'ic's 25 and 29 serve, re-V stand severe handling Vand will not break or crack when used for shipping heavy The invention is not to be understood as Vrestricted to the details set forth, since these pended claims, without departing from the spirit and scope of the invention.
